The Nitto NT420V 305/50R20 is a luxury truck and SUV radial with a 120H service description and an XL (Extra Load) designation. Its asymmetric tread uses larger outer blocks for dry cornering and wide grooves to channel water during wet-road driving.
Manufacturer dimensions are 32.05 inches in diameter and 12.44 inches in overall width, using a measuring rim 9.5 inches wide. Approved rim widths are 8.5 to 11 inches for this 20-inch wheel size. New tread depth is listed at 12.5/32 inch. The non-directional pattern allows cross-rotation where the vehicle and tire configuration permit it. A qualified tire retailer should determine the appropriate rotation pattern.
Maximum single-tire load is 3,086 lb at 50 psi. Before ordering, have a qualified installer confirm wheel compatibility, vehicle load/speed requirements, and steering and suspension clearance. Vehicle-specific fitment requires those checks; select operating inflation using the vehicle placard and applicable load/inflation guidance.
